vINEI?ROVEMEI'J IN OIL-CUPS-AND BEARING-S FOR SPIND/LESI.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that I, EUGENE GoNvEns, of Oswego, New York, have inventednew and useful Improvements in the Construction of Shafts or Spindlesand Steps therefor; and I do hereby declarethat the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, and the letters of reference thereon, "makingpart of this specification.

. In the drawiugs- Figure l is a vertical section of the shaft and step.iugm-e 2 is a side view. Figure 3 is an inside view of the cap.

Figure 4 shows the collar, with the lugs thereon,

byj which the cap is held in position.

The object of my invention is to provide means for lubricating thegudgeon of the shaft, so as, at the same time, to exclude dust andorganic mattei' from the oil-box, and prevent heating and wear, whileeconomizing the lubricating material.

It consists of the parts and combinations hereinafter described.

Iusteadot' making the shaft with a pointed end, as customary, I drill ahole in Vthe end, and in the oilbox or step make'apivot on which theshaft may revolve. The oil-box being larger than the end of the shaft,there is no friction.

Near the` end of the shaft, at a point corresponding with the top oftheoil-box, I place a collar to support the protecting cap. This collar hasprojections or lugs to lit corresponding notches in the inside of thecap, so as to hold the cap inplace, and cause it to revolve with theshaft. rIhe cap is tted closely to the collar, but freely upon theoil-box, so as to prevent friction. It is also movable upon the shaft,facilitating the examination and cleaning or'oiling of the pivot ends.

The hole in the end 0i' the shaft and pivot upon which it revolves areshown at a, fig.. 1.

The collar on the shaft is shown at b, lig. 2, and also detached iu fig.4.

The lugs or projections are indicated at e, figs. 2 and 4.

The cap, moved up on' the shaft, is shown at c, fig. 2, and an insideview is presented in tig. 3. A sectional view is also presented. at o,iig. 1.

By means of this method of constructing shafts lor spindles, .dust andforeign matter are excluded from the pivot end. The cap, revolving withthe shaft, acts as a fau to throw off dirt from the outside. As nowconstructed, oil-boxes are left openl and exposed, forming readyreceptacles for all the dust and dirt created around them. 'Ihe entranceof this dirt is by my method entirely prevented, and the consequentheat-- ing and wear of the pivot end prevented.

What I claim as my invention, and desire to secure by Lettersl Patent,is

' l. The combination of the movable cap and collar b o, iig. 2,constructed substantially as described and for the purposes set forth.

2. The shaft, with hole in the end, and corresponding pivot fixed in theoil-box or step a, g. 1, as described, and for the purposes set forth.

3. The combination of sliding cap c, the spindle f, having a collar b,with lugs c, and the oil-cup g, the cap revolving with the spindle, andnotin'contact with the oil-cup, in the manner and for the purposessubstahtiall y as shown and'described.

In testimony that I claim the above, I have here nuto subscribed my namein the presence of' two witnesses.

Witnesses: E. GONVERS.
